..... Bars, bars, why don‘t you climb the bars
Yes, yes, yes, I want to climb the bars
Good, good, the bars are fun for you
Yay, yay, yay, I like them, ooh!
See, see, Monkey likes the bars
One, two, three, climbing‘s fun, you see!
Yes, yes, yes, you see I‘m climbing now!
Climb, climb, climb, I like it, wow! ....
They don't say "the Monkey likes the bar".
You bought your child a stuffed bunny animal. Is it natural to say to the child:
-"Do you love Bunny?" or "Do you love the Bunny?"
-"See! Bunny likes the shoes" or "See! The Bunny likes the shoes" (I say this as a way to encourage the child to wear the shoes. He sometimes doesn't listen to what I suggest to him.)
So, I guess native people may say "Bunny" without "The" when they want to refer it as a proper name or something.
When to say "Bunny" and when to say "the Bunny"?
